Abstract: 319,775. Hyde, R. W. Sept. 29, 1928, [Convention date]. Thermo-aluminic and like mixtures and metalextracting processes; agglomerating processes. - In a thermo-aluminic mixture, the oxide constituent is in the form of porous grains such as crushed sinter. In the production of iron, iron ores or by-products such as fine borings, mill scale, or other iron oxides or the like may be crushed, screened, mixed with a small amount of fuel, moistened, and sintered by blast-roasting in a thin layer, the resulting sinter being crushed, screened, and mixed with finely-divided or granular aluminium. Additional iron may be added to be melted down during the reaction. Chromium, vanadium, and other metals may be similarly reduced by aluminium, calcium, or other reducing metals.

Title: Improvements in or relating to vibratory barrel finishing machines
IPC: B24B31/06
Filed: 1965-07-06
Abstract: 1,082,329. Vibratory finishing. ALMCO SUPERSHEEN DIVISION OF GREAT BRITAIN Ltd., and C. J. A. KELLARD. July 6, 1966 [July 6, 1965], No. 28586/65 Heading B3D. In the barrel of a vibratory finishing machine there is provided support means capable of supporting an article in such a manner that in operation of the machine the circulation of the chip mass causes the article to rotate about an axis determined by the support means. An elongated article (5) to be finished is secured at each end to a wheel 6 by a stud or spigot extending through a hollow hub (7) of the wheel and receiving a nut (8). U-shaped metal strips 9 are interposed between the wheels and the rubber or neoprene lining 4 of the barrel 1, the diameter of the wheels being less than the internal diameter of the strips 9. After the assembly of article and wheels has been lowered into the barrel, an elongated member 11 is removably secured at each end to the end walls of the barrel. The member 11 has adjacent each end a pair of arms 12, each carrying a roller 13. Finishing media, e.g. stone or other chips mixed with abrasive and/or liquid, is added and the barrel vibrated. The media lifts the article until the wheels 6 contact the rollers; flanges on the rollers locate the assembly axially. The circulation of the chip mass causes rotation of the article. To prevent eddy currents a profiled member 14 may be removably attached to one or both side walls 3 of the barrel. In a modification, each pair of rollers 13 is carried by a cross-piece adjustably secured to the flanges of the side walls of the barrel. The rollers 13 can be replaced by members at each end of the barrel having bearings engaging axial extensions of the hubs 7. For finishing a number of small articles, the wheels 6 may be connected together by angularly spaced longitudinally extending members to which the articles can be attached.

Title: Improvements in and relating to the production of ketenes
IPC: C07C45/88
Filed: 1947-10-31
Abstract: In the production of ketenes by the thermal decomposition of ketones in a reactor constructed of a heat-resistant alloy steel containing both chromium and nickel at least one sulphur containing compound which is liquid or gaseous at 20 DEG  C. is incorporated in the ketone prior to decomposition so that the deposit of carbon on the walls of the reactor is maintained at a negligible amount during the decomposition.  Sulphur containing compounds specified are hydrogen sulphide, ethyl mercaptan, thioglycollic acid, allyl isothiocyanate and carbon disulphide which is preferred.  A preferred amount of sulphur compound is that which will provide 0.1 per cent of sulphur based on the weight of ketone used.  Ketones specified are methyl ethyl ketone, diethyl ketone and acetone which is preferred. Decomposition temperatures are preferably within the range 600-900 DEG  C. and the reactor is preferably purged before and after the reaction by passing a stream of inert gas such as nitrogen therethrough.  In examples, experiments are performed both with and without the addition of sulphur compounds and the carbon deposited in the decomposition of acetone to ketene in stainless steel tubes at 700 DEG  C. is collected and weighed in (1) the steel contained 18 per cent chromium, 8 per cent nickel and 1 per cent titanium in (2) 24 per cent chromium, 16 per cent nickel, 0.5 per cent titanium, 0.9 per cent silicon and 0.8 per cent manganese and in (3), (4) and (5) 25 per cent chromium, 20 per cent nickel and 0.1 per cent carbon and in (1), (2) and (3) 0.1 per cent of carbon disulphide, (4) 0.1 per cent hydrogen sulphide, and (5) 0.2 per cent ethyl mercaptan is added to the acetone prior to decomposition.  In the Provisional Specification there are no limits to the elements from which the reactor may be constructed.ALSO:Reaction vessels made of heat resistant alloy stainless steel containing both chromium and nickel are used in the production of ketenes by the thermal decomposition of ketones (see Group IV (b).

Title: Improvements in and relating to sheet feeding mechanism for gumming, drying or other apparatus
IPC: B65C9/14
Filed: 1921-11-05
Abstract: 192,194. Carlaw, D., and Carlaw & Sons, Ltd., D. Nov. 5, 1921. Coating-machines.-In a gumming or like machine the sheets are fed from the bottom of an inclined pile by a suction separator which is moved to and from the bottom of the pile preferably in an elliptical path, and is also given an angular or rotational motion; the combined motions resulting in the prevention of relative movement taking place between the suction member and the sheet adhering to it. The arrangement is such that the separator can act on the next sheet without waiting until the previous sheet has been wholly withdrawn. The suction device acts in conjunction with a sheet deflector to advance the sheet 'between conveyer bands which in the case of a gumming-apparatus forwards the sheets to a drum containing a channel in which air is circulated to effect the drying. As shown, the sheets 17 are supported between guides 19, 18 on bands 20 which are adjustable for dealing with sheets of different lengths, the bands passing over rollers mounted in arms which can be adjusted to keep them taut. The sheets are gummed by a receptacle 23 formed with a slot and connected by a tube 23<a> to a fountain arranged above the level of the gum-slot. The receptacle is mounted on a lever 24 with a weight 25 which presses the gumming-device against the rear of the pile 17. The 'bottom sheet of the pile is separated by a suction device 16 and is forwarded to a drying apparatus.
